Photocontrolled heterojunctions constructed from holmium single atom modified Mg 1.2 Ti 1.8 O 5 /g-C 3 N 4 with enhanced photocatalytic CO 2 conversion

This work is the first to introduce photocontrolled catalysts into CO 2 RR, and further introduce RE single atom into the catalysts, aiming to optimize the photocatalytic performance by utilizing the synergistic effect of RE single atom and composites.
